【Android】 自定义文件上传列表

创建进度条样式文件（渐变色）

gradient_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/background">
        <shape>
            <corners android:radius="5dp"/>
        </shape>
        <!--    背景颜色-->
        <color android:color="#FFFFFF"/>
    </item>

    <item android:id="@android:id/progress">
        <clip
            android:clipOrientation="horizontal"
            android:gravity="left">
            <shape>
                <corners android:radius="5dp"/>
                <!--  开始颜色，中途颜色，最后颜色-->
                <gradient
                    android:startColor="@color/theme_color_cyan_05"
                    android:centerColor="@color/theme_color_cyan_08"
                    android:endColor="@color/theme_color_cyan"/>
            </shape>
        </clip>
    </item>
</layer-list>

创建List的Item

item_list_folder_progress.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingTop="8dp"
    android:paddingBottom="8dp"
>
    <TextView
        android:id="@+id/textFileName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="测试文件"
    />
    <LinearLayout
        android:layout_marginTop="8dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:orientation="horizontal"
        android:gravity="center"
    >
        <ProgressBar
            android:id="@+id/progress_bar"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="2dp"
            android:progress="90"
            android:max="100"
            android:progressDrawable="@drawable/gradient_progress_bar"
            style="@style/Widget.AppCompat.ProgressBar.Horizontal"
        />
        <TextView
            android:id="@+id/progressText"
            android:layout_marginStart="8dp"
            android:layout_width="30dp"
            android:layout_height="wrap_content"
            android:text="100%"
            android:textSize="12sp"
        />
    </LinearLayout>
</LinearLayout>

创建Dialog页面

dialog_uploader_file_progress.xml

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"

    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/recyclerView"
    android:background="@drawable/rounded_dialog"
    android:orientation="vertical"
    android:paddingBottom="20dp"
>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:orientation="horizontal"
        android:gravity="center_vertical"
        android:background="@drawable/gradient_dialog_top"
        >
        <TextView
            android:id="@+id/dialog_title"

            android:textColor="@color/white"
            android:text="标题"
            android:layout_marginEnd="-50dp"
            android:textSize="20sp"
            />
        <ImageView
            android:id="@+id/dialog_close_view"
            android:layout_gravity="center"
            android:gravity="center"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_marginEnd="10dp"
            android:src="@mipmap/icon_close"
        />
    </LinearLayout>
    <ListView
        android:padding="16dp"
        android:id="@+id/folder_content"
        android:layout_width="match_parent"
        android:layout_height="4000dp"
        tools:ignore="NestedScrolling"
    />
</LinearLayout>

List的对象页面

FileProgressInfo.java

package com.hxtx.august.MyObject;

    private String name;
    private Integer progress;

    public FileProgressInfo(String name, Integer progress) {
